How can I handle URLs with illegal characters such that they don't throw an unhandled exception? I tried an HttpModule but that doesn't catch the error. I'm using IIS6 and .Net 2.0.

I am trying to use a WebClient to get the content of another webform in my project. I am using a WebClient because I want to do this asynchronously, so if there is a better way to do that, I am open to it.My webclient, however, is erroring with the "Illegal characters in path" error. Looking at it in the debugger, I see that this is the URI string I am using:
"PortfolioDetail.aspx?CCSG=True&Open=False&Plcmt=2008-Aug "
I don't see any illegal characters in it... what am I doing wrong?
When I click the button it's giving an error "Illegal characters in path.",instead opening the pdf file
protected void Button2_Click(object sender, EventArgs e)
{
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=TestPage1.pdf");
[Code].....
I have this HttpHandler which works great ONLY for PDF files:
=================================================================
public void ProcessRequest(HttpContext context)
{
HttpResponse response = HttpContext.Current.Response;
[code]...
I'm downloading a binary file from a SQL database to a client machine and want to instead download it to a folder on a server. THe code I'm using is below. How would I change the .AddHeader(I assume) to send the file to a folder on my server rather than the computer running the web page.Protected Sub download(ByVal dt As DataTable)
View 3 RepliesI am using Webhandler to upload images to the server. I want to send the folder name so on that folder the images will save. I am using this URI format and got the below error.
builder.Path = builder.Path.TrimEnd('/')
+ "/Services/FileReceiver.ashx?foldername=" +
folder;
this.Uri
= builder.Uri;
Also I added the following line in the web.config but still having the issue.
<httpRuntime requestValidationMode="2.0" />

I have a MVC application which is called by entering httphandler in the URL. for example my url is likeexaple.com/client.site/__.ashxNow when i enter illegal characers some thing like this: exaple.com/client.site/_||_.ashx . It is throwing an error saying illegal characters in the URL. I tried to handle it in web.config but of no use.So i added global.asax, by redirecting it to some htm file. It works perfect. But when i enter the illega character like this: example.com/client.s||ite/__.ashxIt is showing the error page. How can I handle this. I tried with custom error page at IIS,but of no use.My requirement is to display custom erro page when some illegal character is entered in the URL.

I wants to url rewriting like as subdomain.
For example my website is website.com so that now i wants to url rewriting like
client1.website.com ,
client2.website.com,
client3.website.com,
clientN.website.com
In my website there are list of client whenever click on client my url like this
website.com/client.aspx?client=client1
website.com/client.aspx?client=client2
website.com/client.aspx?client=client3
website.com/client.aspx?client=clientN
Now i wants to url rewriting like as
client1.website.com
client2.website.com
client3.website.com
clientN.website.com
Also whenever once client is registered,After that client can directly open site
I have created my url rewrite handler and its working fine, but on live site i have IIS 6
and its not accepting the subdomain requests
when i type
http://website.com
it works fine but with
http://sub.wesite.com
i got the error Server not found
the project i'm working right now, client wants to make url seo friendly, if any event would enter from the admin section the url should show the name of the event itself.
right now it shows www.--------.com/eventdetails.aspx?id=879878
but the client wants www.---------.com/eventname/
the event comes dynamically every day.

I have 2 asp.net apps, each on a different server and with its own SS2005 db.
What I need is to grab the data entered in a form in app1 and insert that "behind the scenes" into the app2 db.
I suppose I have to do a POST in app1 and intercept that in app2, but since I've not done much http handling yet, I could use some hints or even examples if possible.
The data to be transferred is all strings.
